· JVASP-86181· Ti4AlN3

Ti4AlN3 is a titanium aluminum nitride compound that belongs to the family of ceramic-metallic nitride materials, combining titanium and aluminum with nitrogen to create a hard, refractory phase. This material is primarily of research and development interest for high-temperature structural applications, coating systems, and wear-resistant components where extreme hardness and thermal stability are required. Its notable advantage over monolithic ceramics or traditional alloys is the potential for improved fracture toughness and thermal shock resistance while maintaining exceptional hardness at elevated temperatures, making it relevant to aerospace, cutting tool, and thermal barrier coating development.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
